Dell PowerEdge XE9780L and XE9785L memory kit

This 512GB kit contains eight 64GB DDR5 5600 registered ECC RDIMM modules built for Dell PowerEdge XE9780L and XE9785L rack servers. It targets administrators who need maximum registered capacity in those specific platforms.

Registered ECC RDIMM with 288-pin DDR5 interface

Each module uses a 288-pin DDR5 registered DIMM form factor with on-board ECC and a 4Rx4 organisation. The registered buffer reduces electrical load on the server memory controller, while the lack of heat spreaders keeps the profile compatible with dense rack chassis airflow.

512GB total capacity at DDR5 5600 CL46 1.10V

The kit delivers 512GB across eight modules running at 5600 MT/s with a CAS latency of 46 at 1.10 volts. Servers that cannot accept 4Rx4 registered DDR5 RDIMMs or that require a different voltage will not support this configuration.

Questions about this item

What DDR5 speed does the PC5-44800 rating cap the kit at in practice?

The modules run at DDR5 5600, which is the effective ceiling of the PC5-44800 specification.

What physical slot and module count does this 8 x 64 GB kit require?

It uses eight 288-pin DDR5 RDIMM slots, one per 64 GB module.

How are the registered ECC modules installed, and what step is often missed?

Power down the server, open the chassis, align each module with its 288-pin slot and press until the ejector tabs click; the step often missed is confirming the BIOS recognises all 512 GB after reboot.
